Try selecting a movie and open the Info panel. Do any of the dates correspond to the date created?
no, none of the 3 dates in EM2 (created, modified,archived) has the correct date. they correspond to when the file was copied to my Mac, or cataloged by EM2.
reading the same file with Canon's free "ImageBrowser" utility, displays the correct original capture date and time.
this capture date & time is also contained in the separate THM sidecar file (readable by EXIF extraction apps like EXIF Viewer) BUT the Canon utility can extract the correct date & time from the AVI file even when this sidecar file has been deleted.
